Different tunnel, better Shocks in rear, much better shocks in front. The Rear suspension rails are also reinforced, the arms were supposed to be reinforced however they decided to cut that before production, too bad I cracked my rear arm. Anyway the rest is cosmetic, a different windy, and some stickers. The front shocks are worth the extra they charged. The rear improvement is a bonus. If you are comparing the two it would be worth an extra 500 easily maybe 800 all other things being equal. You could get a standard and spend the rest on revalves and shock add ons, but you wouldn't get the other stuff as well.
